Security forces kept their distance and stick-wielding activists of the hardline Sunni Tehreek movement, which organised the funeral prayers, controlled the crowd.

The coffin was then taken in its flower-strewn ambulance some 20km (12.5 miles) north to Qadri's ancestral village on the eastern outskirts of Islamabad.

Mumtaz Qadri was hailed as a hero by some Islamist groups

His execution on Monday prompted protesters to take to the streets in cities in Pakistan.

But the rallies in Karachi, Lahore and Islamabad were mostly peaceful. Demonstrators burned tyres and chanted slogans, as well as blocking some roads into Islamabad.

When news of Mumtaz Qadri's execution broke, Pakistanis were glued to their television sets in anticipation of riots on the streets by his supporters.

But what protests there were were sporadic and not well attended - and the mood of the mourners at Tuesday's funeral was equally restrained.

More importantly, news anchors of dozens of Pakistani television channels, who would normally be hysterical at such a development, seemed not to notice. So why the media silence when there was a golden chance to boost ratings?

"Obviously, they have been sent a piece of advice by an authority they can't ignore, and that authority is definitely not the political government," says Ayesha Siddiqa, a defence and political analyst.

For most in Pakistan, that could only be the military.

Qadri was executed at 04:30 local time (23:30 GMT) at Adiala jail in Rawalpindi on Monday.

He had trained as an elite police commando and was assigned to Salman Taseer as his bodyguard. Qadri shot the politician 28 times at an Islamabad market in January 2011 and was sentenced to death later that year.

He claimed it was his religious duty to kill the minister, who was an outspoken critic of Pakistan's harsh blasphemy laws and supported liberal reforms.

Pakistan has seen Islamist groups grow in influence in recent years and several high-profile blasphemy cases.

Blasphemy is an extremely sensitive issue in Pakistan and critics argue that blasphemy laws are often misused to settle personal scores and unfairly target minorities.
